Hi all
before part P came in what did you do on a CU change we did the same as every body else 16th edition install all circuits turn it on if RCD holds the system was fine.
Only difference now is part P & don't get me wrong I am all for it as long at it policed properly which it's not. I still know people who do cash installs who do a couple of test mainly LE Ne M ohms & earth tests & F... All else. It still goes on.
Part P or no Part P, I wouldn't install a new CU without some pre install tests, nor miss out all the circuit testing, nor issueing an EIC.
